Wanted any DDR (Dance Dance Revolution) Games!

Yeah, I know this is a long shot. My niece is wanting any of the DDR games for Christmas this year. Her dad has already got for her a really sweet dance pad, but it did not come with a game. Thats where I come in the equation.

If you have any for sale/trade let me know. Doesn't have to be the newest one, just any of the Ps2 ones will do. I can Paypal immediately for quick shipping--
